The book progresses by first establishing core concepts, like defining humor in a non-human context and tackling the challenges of studying subjective experiences across species. It then dedicates chapters to specific animal groups, such as birds, mammals, and insects, showcasing examples of these humorous behaviors. For example, the book highlights the role of play and mimicry in social development and learning, as well as the function of courtship rituals as displays of fitness. By combining scientific rigor with accessible storytelling, Funny Animals encourages a fresh perspective on the intelligence and emotional lives of animals.
